SILK-=CLAMP.

SPECIFICATION forming part of Letters Patent No. 664,885, dated January1, 1901.

Application filed May 2, 1900. Serial No. 15,228. (No model.)

To aZZ whom it may concern:

Be it known that I, JAMES JOSEPH MC- GRATH, a citizen of the UnitedStates, and a resident of Brookhaven, in the county of Lincoln and Stateof Mississippi, have invented new and useful Improvementsin Silk-Clamps,of which the following is a full, clear, and exact description.

The invention has for its object to provide a clamp adapted to bind abolt of silk and retain the folds in proper position while exhibitingthe goods.

In carrying out my invention I provide main clamp-arms and auxiliaryinner clamp-arms to obtain a clamping action at two distant points, theinner clamp-arms being of novel form to prevent them from making animpression on the silk when several bolts are superposed.- This specialarrangement of these inner clamp-arms is to be particularly ob served asforming an important element in eifecting the purpose of the devicewithout danger of deteriorating the silk.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective View representing my improved clamp applied toa bolt of silk, the latter being shown partly open to display the goods.Fig. 2 is a side elevation of the clamp on a larger scale, showing itsposition on the bolt; and Fig. 3'is a perspective View of the clampdetached from the bolt.

The main clamp-arms A are formed in a single piece of suitable springmetal, united at the U-bend a, and have sufficient length to take aproper bearing on the bolt D. The inner clamp-arms B B are continuouswith the main arms and extend inwardly toward the U-bend a. Oneauxiliary clamp-arm B, it

will be observed, extends considerably beyond the companion arm B, andits projecting end I) is oifset toward the arm B, providing an extendedsurface beyond the said arm B and forming at the base of the offset parta depression I) at a point adjacent to the end of the shorter arm. Theresult of this arrangement is that neither of the auxiliary arms will bepressed into the silk when several bolts are superposed, and as theinner clamp-arms relieve or modify the clamping action of the ends ofthe outer arms the bolts and clamps will lie so nearly fiat as not toproduce indentations in the silk. In exhibiting the goods the clampspreserve the original folds and will prevent the formation of additionalcreases, which without the clamp are a frequent occurrence and a causeof deterioration of the goods, necessitating a lowering of the sellingprice.

Having thus described my invention, I claim as new and desire to secureby Letters Patent l. A clamp for silk and the like, comprising mainclamp-arms, and auxiliary clamp-arms carried by the main clamp-arms andranging in the opposite direction, said auxiliary clamparms being ofunequal length and the longer one being offset, presenting a depressedportion opposite the shorter arm and affording a broad projecting endbeyond said shorter arm.

2. A clamp for bolts of silk and the like, comprising main and auxiliaryclamp-arms, the main arms being convergent to form clamping-surfaces,the said arms being curved outward at the outer ends and beingreturnbent, forming the auxiliary arms, the latter ranging inward fromthe outwardly-curved ends of the maixrarms, the inner ends of theauxiliary arms forming clamping-surfaces.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
